One – old (er) and slightly overweight. She has had a knee tendon replaced. She is calm. Goes thru the day slowly. Not much gets her excited. Maybe food. She is well trained and obedient.
The other dog – young and excitable. Always moving. Easily bored. Chews things up without realizing the consequences. She is “in training”. Constantly in trouble.
Hanging with the old dog seems to calm young dog down.
Hanging with the young dog keeps old dog moving and engaged.
Some of us old dogs need to pay more attention to the young pups around us.
Some of the young pups need to stop and watch the old dogs – watch and learn.
